OBJECTIVE Stereotactic radiosurgery for vestibular schwannoma entails uncertain long-term risk of tumor recurrence and delayed cranial neuropathies. In addition, the underlying histopathologic changes to the tumor bed are not fully characterized. We seek to understand the clinical and histologic features of recurrent vestibular schwannoma after stereotactic radiation therapy. STUDY DESIGN Ret...

Treatment of recurrent glioblastoma is still challenging. Stereotactic radiosurgery has been accepted as a treatment option for recurrent glioblastoma after standard chemotherapy and irradiation. However, the efficacy of stereotactic radiosurgery at recurrence has been limited, mainly due to the highly infiltrative nature of the tumor which makes the lesion difficult to define as the target. To...

The aim of this study was to describe our initial experience with a gold flexible linear fiducial marker and to evaluate the safety and technical and clinical efficacy of stereotactic body radiotherapy using this marker for malignant liver tumors. Between July 2012 and February 2015, 18 patients underwent percutaneous fiducial marker placement before stereotactic body radiotherapy for malignant...

BACKGROUND The aim of this study was to assess the diagnostic performance of stereotactic core needle breast biopsy using spring-loaded or vacuum-assisted techniques for impalpable microcalcification lesions in Taiwanese women. METHODS We retrospectively reviewed the data of patients who received stereotactic core needle breast biopsy for impalpable mammographic microcalcification lesions fro...

Our objective was to provide guidelines about the use of stereotactic radiosurgery in symptomatic patients with imaging-identified arteriovenous malformations (AVMs) of the brain. We reviewed evidence-based medicine and clinical experience with radiosurgery for AVM of the brain to develop guidelines and provide scientific foundation for patients and physicians. Major recommendations include the...

OBJECTIVES Minimally invasive procedures for treating temporal lobe epilepsy have been investigated recently, namely stereotactic and gamma knife amygdalohippocampectomy (AHE). However, the results are not fully satisfactory. Our aim was to evaluate efficacy and side-effects of stereotactic AHE mimicking the neurosurgical procedure in terms of extent of the lesion. METHODS 16 consecutive pati...

BACKGROUND Stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT) are highly conformal, high-dose radiation treatment techniques used to treat people and dogs with brain tumors. OBJECTIVES To evaluate the response to SRS- and SRT-treated tumors using volume and perfusion variables and to measure the survival times of affected dogs. ANIMALS Prospective study of 34 dogs with evid...
